MARKER.

SPECIFICATION forming part of Letters Patent No. 499,889, dated June 20, 1893. Application filed December 8, 1892. Serial No. 454,487. (No model.)

To all whom it may concern: I

' Be it known that 1, JOHN T. RUSH, a citizen of the United States, residing at Tyrone, in the county of Blair and State of Pennsylvania, have invented a new and useful Shingle-Marker, of which the following is a specification.

This invention relates to shingle markers; and it has for its object to provide certain improvements in portable shingle marking devices, whereby the construction thereof shall be simplified, so as to allow for the ready attachment and detachment thereof to and from an edger or jointer.

To this end the invention primarily contemplates certain improvements in the machine disclosed in my former Patent No. 481,198, whereby the shingle is marked on its under side as the same passes through the regular process of jointing without impediment to such process, and with this in View it is primarily the object to provide simplicity, durability and efficiency of construction.

With these and many other objects in view. which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed.

In the accompanying drawings:-Figure 1 is a perspective view of a shingle marker constructed in accordance with this invention attached to an edger or jointer. Fig. 2 is a central longitudinal sectional view thereof. Fig. 3 is a detail in perspective of the marking device proper. Fig. 4 is a similar view of a shingle operated upon by the marker.

Referring to, the accompanying drawings, A represents a part of an edger or jointer which is adapted for'the wellknown uses alongside of the edger wheel or saw B. The edger A, is provided atone end with an upwardly extending right-angularly disposed gage board 0, which serves to receive the butt of the shingle D, in order to guide the same across the edger, while the course-mark E, is being made thereon, by the marking device attached to the edger or jointer. The shingles are marked in order to facilitate the laying thereof, without the employment of the usual gage line which is used for aligning the shingles. The edger A, is recessed at one edge or side as at F, which recess is inclosed at the top by the attachment plate or table G. The attachment plate G, is secured upon the top of the edger or jointer, with one edge thereof resting against the end gage board C, and is provided with a slot or opening H, therein. The attachment plate G, carries or has secured to the under side thereof the spring arm I. The spring arm I, is secured atone end as at 2', to said attachment plate or table and is provided with a longitudinally disposed slot J, and a right angularly disposed clamping end or arm K, which normallylies under or partly within the slot or opening H, in the plate or table, and the said arm is provided with a threaded perforation L.

Mounted for adjustment on the under side of the arm I, is the adjustable clamping plate through the perforation n, of the arm N, and

engages the threaded perforation L, of the spring arm, and thereby provides means for securely clamping the marking block or stick P,. between the two clamping arms. The block or stick P, is of any suitable marking material, such as chalk or lead, and is normally projected by the spring arm 2', through and above the slot or opening H, in the attachment plate or table G.

In operation, during the process of jointing, the shingle is passed transversely over the table G, the butt end of the same riding against the gage board 0. The tension of the spring I, holds the marking block P, in contact with the under side of the shingle and makes the necessary course mark E, thereon.

From the foregoing it will readily be seen that the herein described device is easily operated, easily attached to an edger or jointer to secure the desired result, and it will also be apparent that by reason of having the marking arm arranged under the table, the process of edging or jointing the shingles is in no wise interfered with.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in- 5 vention.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

1. In a shingle marker, the combination of [0 an attachment plate or table having aslot or opening, a gage board arranged at one end of said plate or table, a spring arm secured at one end to the under side of the plate or table, a clamp adjnstably attached to said 1 r 5 spring arm, and a marking blockior stick re-H movablyheld in position between said clamp and the spring arm, said block or stick normally projecting through the slotor opening in the attachment plate ortable, substantially 20 as set forth.

2. In a shingle marker, an attachment plate i or table having a slot or opening, the gage board arranged at one end of said plate or attachment plate or table, substantially as set forth;

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in the presence of two witnesses.

JOHN T. RUSH.
